[0033] As Figures 1 to 8 shown, the technical solution of the present application provides a capacitor bending and broken needle device, including: a workbench 1; a capacitor placement seat 3, which includes a fixed vertical plate 31, a capacitor placement plate 32, and a guide needle truncation beam 33. The fixed vertical plate 31 is fixed on the workbench 1, the capacitor placement plate 32 is detachably connected to the top of the fixed vertical plate 31, a bending plate 321 is provided upward at the edge of the capacitor placement plate 32, and the guide needle truncation beam 33 is detachably connected to one side of the fixed vertical plate 31. Among them, the vertical surface of the bending plate 321 far from the capacitor placement plate 32 is flush with the vertical surface of the guide needle truncation beam 33 far from the fixed vertical plate 31; a block-shaped press head 2 is provided on one side of the capacitor placement seat 3, and the horizontal distance between the block-shaped press head 2 and the bending plate 321 is equal to the diameter of the capacitor guide needle 41. The block-shaped press head 2 is vertically translated from above the bending plate 321 to the guide needle truncation beam 33 under an external force; a cutting module, including a cylinder 5 and a moving cutter head 6 provided on one side of the capacitor placement seat 3. The cylinder seat of the cylinder 5 is fixed on the workbench 1, and the telescopic column of the cylinder 5 is detachably connected to the moving cutter head 6. The height of the cutter head end of the moving cutter head 6 is flush with the bottom edge of the guide needle truncation beam 33, and the moving cutter head 6 horizontally displaces and contacts the bottom edge of the guide needle truncation beam 33 under the action of the telescopic column of the cylinder 5.

[0034] In this technical solution, several fixing holes are provided on the upper surface of the workbench 1. A vertical plate fixing base 311 is provided at the bottom of the fixed vertical plate 31, and a bolt hole is provided thereon. The vertical plate fixing base 311 is fixed to the workbench 1 by bolts. The capacitor placement plate 32 can be connected to the fixed vertical plate 31 by bolts. Among them, the capacitor 4 is placed on the capacitor placement plate 32 by an external manipulator structure or manually, and the capacitor lead 41 horizontally extends out of the bending plate 321 and is placed on the bending plate 321. A cylinder or other form of transmission device is provided at the top of the block-shaped press head 2 to enable it to perform vertical reciprocating movement. When the block-shaped press head 2 moves vertically, it forces the capacitor lead 41 to bend downward with the contact point between it and the bending plate 321 as the bending point, and contacts the vertical surface of the lead cutting beam 33. When the press head block 2 is lifted, the bent capacitor lead 41 remains in contact with the lead cutting beam 33.

[0035] In this technical solution, the cylinder block of the cylinder 5 is fixed to the workbench 1 through a cylinder fixing base 51. The telescopic column of the cylinder 5 faces the direction of the capacitor placement seat 3. The end of the telescopic column of the cylinder 5 is detachably connected to a cylinder push plate 50. The moving cutter head 6 is a wedge-shaped block with a sharpened end and a horizontal upper surface. The sharpened cutter head end faces the capacitor placement seat 3. The rear part of the moving cutter head 6 is a moving cutter head fixing block 61, which can be detachably connected to the cylinder push plate 50 by bolts. Optionally, the height of the moving cutter head 6 can be adjusted by adjusting the fixing position of the moving cutter head fixing block 61 on the cylinder push plate 50 or adjusting the height of the cylinder fixing base 51. The telescopic column of the cylinder 5 horizontally pushes the moving cutter head 6. The end of the moving cutter head 6 and the lower edge of the lead cutting beam 33 jointly cut off the bent capacitor lead 41. At this time, the manipulator or manual labor takes away the processed capacitor 4 and places the next capacitor 4 flat on the capacitor placement plate 32. The reciprocating vertical movement of the block-shaped press head 2 and the reciprocating pushing and pulling action of the cylinder 5 on the moving cutter head 6 involved in the process of the capacitor lead 41 from straight to bent and then to cut off are common practices in automated operations. Using this device can greatly improve production efficiency.

[0036] In another technical solution, a vertical plate notch 310 is provided in the upper part of the fixed vertical plate 31. The lead cutting beam 33 is horizontally fixed in the vertical plate notch 310. The bending plate 321, the lead cutting beam 33, and the side of the fixed vertical plate 31 facing the block-shaped press head 2 are flush. In this technical solution, the fixed vertical plate 31 is a plate body with a certain thickness. Among them, the capacitor placement plate 32 is located at the top or one side of the fixed vertical plate 31. The lead cutting beam 33 is connected to the fixed vertical plate 31 by bolts.

[0037] In another technical solution, a guide pin avoidance groove 3211 corresponding to each capacitor guide pin 41 is formed in the upper edge of the bending plate 321. When the capacitor 4 is placed, the capacitor guide pins 41 can naturally fall into the guide pin avoidance grooves 3211, so that the capacitor guide pins 41 can be prevented from having horizontal displacement due to other factors during the bending process, resulting in deviation of the length after truncation.

[0038] In another technical solution, fixing vertical grooves 312 are formed in the vertical sides on both sides of the fixed vertical plate 31. Vertical adjustment blocks 322 are vertically and downwardly connected to both sides of the capacitor placement plate 32. The vertical adjustment blocks 322 are slidably matched in the corresponding fixing vertical grooves 312. Threaded adjustment block fixing holes 3220 are formed in the two vertical adjustment blocks 322 opposite to each other. When adjusting the installation height of the capacitor placement plate 32, first lift the capacitor placement plate 32 along the fixing vertical groove 312. After the capacitor placement plate 32 is lifted to an appropriate height, a fixing pin with a matching thread is pushed against the vertical surface of the fixing vertical groove 312 through the adjustment block fixing hole 3220 to complete the fixation. Optionally, a plurality of pin holes which are arranged at intervals and have the same diameter as the adjustment block fixing hole 3220 can be formed in the fixing vertical groove 312. After the capacitor placement plate 32 is lifted to an appropriate height, the fixing pin is passed through the adjustment block fixing hole 3220 and the pin hole to complete the fixation.

[0039] In another technical solution, a rectangular depression area 3212 is recessed in the vertical surface of the bending plate 321 facing the block-shaped pressing head 2, and the width thereof is greater than the maximum distance between the guide pin avoidance grooves 3211. During the downward bending process of the capacitor guide pins 41, it is prevented from being in force contact with the side wall of the bending plate 321, so that after the block-shaped pressing head 2 is lifted, the capacitor guide pins 41 are bent back after the force is released, resulting in inaccurate truncation positions.

[0040] In another technical solution, a pressing head roller 21 is rotatably connected to the bottom of the block-shaped pressing head 2. The distance between the outer circumference of the pressing head roller 21 and the bending plate 321 is equal to the diameter of the capacitor guide pin 41. A strip-shaped groove is formed at the bottom end of the block-shaped pressing head 2. The pressing head roller 21 is connected to the block-shaped pressing head 2 through a roller shaft 210. During the downward pressing process of the block-shaped pressing head 2, the pressing head roller 21 is always in contact with the capacitor guide pins 41. The pressing head roller 21 only generates a downward force on the capacitor guide pins 41 to avoid any friction and also avoid scratching the coating on the capacitor guide pins 41.

[0041] In another technical solution, a slide rail 7 is fixed between the fixed vertical plate 31 and the cylinder 5. The length and direction of the slide rail 7 match the movement track of the moving cutter head 6. A slider 72 is fixed to the bottom surface of the moving cutter head 6. The slider 72 is slidably matched on the slide rail 7. The slide rail 7 is fixed to the workbench 1 by a plurality of slide rail fixing seats 71 with adjustable heights. While the moving cutter head 6 is pushed by the cylinder 5, it is restricted by the lower slider 72 below to avoid displacement in other directions outside the movement track, ensuring that the top surface of the moving cutter head 6 is always flush with the lower edge of the guide pin cutting beam 33 during the reciprocating push and pull process, and ensuring that the capacitor guide pin 41 is accurately cut off.

[0042] In another technical solution, a cutting beam fixing block 331 is connected to each end of the guide pin cutting beam 33. The cutting beam fixing block 331 is bolted to the side of the fixed vertical plate 31 facing the block-shaped pressing head 2. The distance between the two cutting beam fixing blocks 331 is greater than the width of the moving cutter head 6. In this technical solution, a through hole is provided in the cutting beam fixing block 331, and a fixing bolt 34 is used to connect the cutting beam fixing block 331 and the fixed vertical plate 31. The end of the moving cutter head 6 can pass through between the two cutting beam fixing blocks 331 and extend forward until it contacts the guide pin cutting beam 33. Optionally, a limiting cross beam 332 is connected below the guide pin cutting beam 33 between the cutting beam fixing blocks 331. The moving cutter head 6 is a wedge block with a horizontal top and an inclined bottom. When it continues to move forward after cutting off the capacitor guide pin 41, the limiting cross beam 332 plays a role in blocking the inclined bottom surface of the moving cutter head 6.

[0043] In another technical solution, the distance between the two cutting beam fixing blocks 331 is less than the width of the bottom of the block-shaped pressing head 2, and the downward movement of the block-shaped pressing head 2 is blocked by the cutting beam fixing blocks 331.

[0044] The number of components and the processing scale described here are used to simplify the description of the present invention. The application, modification, and variation of the present invention are obvious to those skilled in the art.

[0045] Although the embodiments of the present invention have been disclosed as above, it is not limited to the applications listed in the specification and embodiments. It can be fully applied to various fields suitable for the present invention. For those familiar with the field, additional modifications can be easily made. Therefore, without departing from the general concept defined by the claims and the equivalent scope, the present invention is not limited to specific details and the illustrated and described examples here.
